Quick Access Recorders
Would anybody be able to help me with some questions on QARs as my aircraft tech manual doesn't even mention them!
1 Where do they obtain their electrical power from,and do they keep functioning when there is limited electrical generation?
2 Where do they obtain the data to be recorded from and what data is recorded?
3 Is there any way spurious data could be recorded,e.g data from a faulty adc?
4 If the data is used for FDM and possibly disciplinary action would there be any way to prove the recorded data was incorrect?
My old Airbus sometimes gives conflicting analogue and digital readouts of information so perhaps the data being sampled may not be accurate.
